The effect of pre-sowing magnetic biostimulation of wheat grains on germination and yield is presented. Two magnetic exposure doses were used. The results show that a magnetic field influenced the germi- nation of wheat seeds. The treated seeds germinated faster than untreated ones. Also, the infiltration rates of water by treated and untreated seeds were almost the same. The germination capacity depended on magnetic exposure dose and moisture content. The field tests revealed that the pre-sowing magnetic biostimulation increased the crop yield in case of both investigated wheat cultivars. The yields were higher than control for Henika cultivar by about 37 % ( D1 = 2880 J m-3s, exposure dose ) and 25.5 % (D2 = 5760 J m-3s, exposure dose) and for Jara cultivar about 19 % (D1 = 2880 J m-3s) and 21.3 % (D2 = 5760 J m-3s). Also, the percentage of gluten in the flour for both wheat cultivars was greater than the control.
